WHEN YOU'RE A TEENAGER THE PROM CAN BE A BIG DEAL AND AN EXPENSIVE DEAL. THE COSTS OF THE TICKETS AND THE DRESS AND THE SHOES AND THE FLOWERS, NEARLY OUT OF REACH. WELL, SHANNON PERRINE TONIGHT WITH THE SO-CALLED PROM ANGEL WHO MADE SURE THE PROM WAS IN REACH FOR A PENN HILLS HIGH SCHOOL SENIOR. Reporter: SOMETIMES YOU FIND YOURSELF WONDERING IF THERE ARE GOOD PEOPLE IN THE WORLD. PART OF THE PROBLEM YOU DON'T ALWAYS HEAR ABOUT IS THE GOOD PEOPLE WORK THEIR MAGIC QUIETLY, MYSTERIOUSLY AND ANONYMOUSLY. SHE WANTED THIS DRESS -- I TRIED ON FOUR TO FIVE DRESSES AND IT WAS JUST MY FAVORITE ONE. Reporter: HER DAD TRIED TO STEER HER TOWARDS THE LESS EXPENSIVE ONES. THREE YEARS AGO I LOST MY JOB AND I'VE BEEN, YOU KNOW, LOOKING, LOOKING, LOOKING FOR SOMETHING STEADY, PERMANENT. AND HAVE BEEN WORKING PART-TIME HERE AND THERE. Reporter: MONEY IS TIGHT. MEGAN DOES HAVE A PART-TIME JOB, BUT HER DAD DID NOT WANT HER TO PAY FOR THE DRESS. HE DIDN'T WANT ME TO DO THAT BECAUSE HE WANTED TO AFFORD IT AND EVERYTHING. I WAS JUST LIKE, WELL, I UNDERSTAND YOU HAVE TO PAY THE MORTGAGE AND EVERYTHING. IT'S NOT A BIG DEAL IF I PAY FOR IT. Reporter: IN THE MIDDLE OF THE DISCUSSION OVER PAYING FOR THE $200 DRESS -- THEY CAME BAND ANCK AND HANDED ME THE RECEIPT. MY MOM WENT TO THE FRONT OF THE STORE AND ASKED, DID YOU PAY FOR THIS YET? AND THEY WERE BOTH LIKE, NO, WE DIDN'T PAY FOR ANYTHING YET. THEY SAID THE DRESS IS PAID FOR. Reporter: A BRIDE SETTLING THE BILL ON HER WEDDING DRESS HERE AT DAVID'S BRIDAL WAS IN EAR SHOT OF MEGAN AND HER FAMILY. WE BELIEVE SHE OVERHEARD A YOUNG LADY GETTING HER PROM DRESS TALKING ABOUT, YOU KNOW, MAYBE GOING THROUGH SOME TOUGH TIMES. WE'RE NOT SURE WHAT THE WHOLE CONVERSATION WAS BUT WHAT HAD HAPPENED WHEN THE BRIDE GOT UP FRONT TO PURCHASE THE DRESS. Reporter: THE BRIDE PAID THE BILL AND SAID, JUST TELL HER IT WAS FROM HER PROM ANGEL AND THEN QUIETLY SLIPPED OUT. SHE WILL NEVER KNOW HOW THANKFUL MEGAN AND HER FAMILY ARE OR THE IMPACT IT WILL HAVE INTO THE FUTURE. IF I SAW A YOUNG GIRL WHO WANTED A PROM DRESS AND I WOULD SAY, I WILL PAY FOR IT IMMEDIATELY. Reporter: MEGAN HAS HER KNOCKOUT DRESS AND ALL SHE NEEDS NOW IS A DATE. YEAH, SHE DOES HAVE SOMEONE IN MIND. I'M GOING TO LET YOU KNOW WHEN
